SPECIFICATION forming part of Letters Patent No. 392,118, dated October 30, 1888.

Application filed January 23, 1888. Serial No. 261,602. (Nomodeh) To all whom it may concern.-

Be it known that I, THOMAS D. HAMMOND, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Machines for Forming Corners for Coffins or Gaskets, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the manufacture of the base-moldings of the rounded corners of burial-caskets. Such moldings are difficult to make, owing to the inclination of the side and end walls of the casket and corresponding inclination of the corners requiring a peculiar shape of said corner-moldings.

The object of this invention is to manufacture the aforesaid corner-moldings in an expeditious, accurate, and perfect manner; and to that end my invention consists in the novel construction and combination of devices for holding the work in its various requisite positions in relation to the saw, as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a top plan view of my invention. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical transverse section on line as 00, Fig. 1. Figs. 4 and 5 are top plan views of the device for holding the block from which the moldings are to be cut. Fig. 6 is an elevation of the same. Fig. 7 is a top plan view of the device for holding the molding during the operation of trimming the top edges thereof. Fig. 8 is Fig. 9 is a transverse section on line 3 y, Fig. 1, and Fig. 10 is an end elevation of the abrading-cylinder, by means of which the side surfaces are finished.

Similar letters of reference indicate corresponding parts.

A denotes the work-table, and S the bandsaw working through a slot, 6, in said table.

.Upon the table is movably mounted the bedplate B, which carries the devices by which the work is held to the saw, and in order to allow said devices'to be brought successively in their requisite operative positions and properly sustain them in said positions I provide the table with a series of holes, jj, for the reception of the clamps K K,by which to fasten the bed-plate B to the table A, as shownin Fig. 1 of the drawings.

To one portionpreferably the central portion-of the bed-plate B and axially parallel with the saw S, I pivot a circular plate, T, which is rotatable in a plane at right angles to the saw. On one side of the top of this plate I hinge another plate at one of its edges, which plate constitutes the holder U of the block to be operated on. This holder is supported adjustably in an inclined position by means of a set-screw, r, passing vertically through the holder U, near the free edge thereof, and resting upon the subjacent plate T, as shown in Fig. 3 of the drawings. To the top of the hinged side of the holder is secured a gage, t, against which to rest the work to be operated on.

To another portion of the bed-plate B, I pivot axially parallel with the saw S another plate, 1?, which is likewise rotatable in a plane at right angles to the saw. The top of this plate is formed with segmental bearings a a at opposite sides of the center of the plate and inclined from the center outward. The segmental edges of the said bearings are concentric with the axis of the plate and lean outward and have secured to them segmental plates or restsRR, against which to place the work to be operated on, as hereinafter de scribed, the work being held against the rests by clamps or spring-arms b b, as shown in Fig. 7 of the drawings.

Another portion of the bed-plate B is provided on its top with horizontal guides au,on which is mounted a slide, 0, having in its under side longitudinal grooves which the said guides enter, as illustrated in Figs. 2 and 3 of the drawings. Said slide is provided with a central longitudinal vertical slot, 0, for the passage of the saw S, and the longitudinal sides of the slide are inclined. To the top of the slide at opposite sides of the slot g are hinged cheek-pieces co, the exteriors of which are convexed transversely. By means of setscrews f f, passing through said cheek-pieces and resting on the sides of the slide 0, the cheek-pieces are supported adjustably in inelined positions. The check-piece c on one side of the slide has adjustably connected to it a gage, d, on which to rest the work to be operated on, said gage being provided with vertical arms 47. 17 provided with longitudi nal slots, through which the attaching-screws it (7 pass. Near the front end of the cheekpiece 0 is another gage or rest, m, pivoted to the lower portion of said cheek-piece and extending toward the top thereof, and provided at its upper end with a forward extension, at, which is provided with a segmental slot, at", for the reception of the screw, by which it is adjustably secured to the cheek-piece.

On still another portion of the bed-plate B are mounted two posts, E E, in which is journaled a shaft, F, and to this shaft between the posts is secured the abrading-cylindcr D,faced on its convex side with sandpaper or other suitable abrading material. A pulley, I is attached to the end of the shaft for the recep tion of the driving-belt. At oncside of the cylinder 1) is apost, Z, secured to the bed-plate .1, and on the top of this post is pivoted the gage h, which lies across the top of the abrading-cylinder, and has secured to its free end a vertical plate, a, which enters loosely into a slot in the head Z of a post, Z, secured to the bed-plate 1". A set-screw, o, is inserted trans versely into the head Z and engages the plate a, and serves to hold the gage h adjustable in its position in relation to the line of the cyl inder D.

The operation of my invention is as follows: First, I adjust the bed-plate B on the table A, so as to bring the edge of the plate T near the saw S, and place upon the holder U a wooden block, L, which is of approximately the same width and thickness as the length and height of the molding to be formed, said block being placed with the base of one of its longitudinal sides against the rest or gage t,and after moving it forward a sufficient distance to bring the end thereof within the range of the saw the plate T is turned on its pivot to cause the saw 8 to pass transversely through the block and trim the end thereof to a shape corresponding to the outer side of the molding to be formed. After that the block L is successively moved forward each time a distance equal to the kerf of the saw and thickness of the molding to be formed. The inclination of the block Z, comhincd with its horizontal rotary motion across the saw S, produces the requisite peculiar winding segmental shape of the molding for one corner of the casket, and by reversing the holder U and presenting the opposite end of the block L to the saw a molding of proper shape for the opposite corner of the casket is produced. I next trim the top edges of the aforesaid moldings by placing the same with their bottom edges in the beveled bearings a a of the plate 1?, and with the convex sides of said moldings against the concave rests R It, in which position they are sustained by the clamps b I), the bed-plate B being shifted 011 the table, so as to bring the edge of the plate 1 near the saw S,and then by turning the said plate on its pivot the saw trims the top edges of the moldings, as illustrated in Figs. 7 and 8 of the drawings. After this is accomplished I shift the bed-plate B on the table A so as to bring the slide 0 in a position to stand with its longitudinal slot 0 in range with the saw S. I then place each piece of molding sepa rately endwise, first on the check-piece c,with the molding I resting on the bed-plate B, as illustrated in Fig.3 of the drawings,and in this position I carry the slide 0 with the molding I toward the saw S until the latter has trimmed the upper end of the molding. I next retract the slide and place the molding I on the cheekpicce c, with the trimmed end of the molding resting against the gage d, and then by moving the slide with the molding to the saw the second end of the molding is trimmed off. The molding is then in its requisite shape, and only requires smoothing and finishing, which are effected by placing it with its concave side on the cylinder D, as represented in Fig. 10 of the drawings. Said concave side, being askew or winding, requires the molding to be placed obliquely on the cylinder, and, inasmuch as the moldings at opposite corners are askewcd reverse, the different corner-moldings require to be placed at different angles on the cylinder. In order to properly guide the moldings in the operation of finishing them I set the gage h at the proper angle and hold the edge of the molding against said gage.

Having described my invention, whatIelaim as new, and desire to secure by Letters Patent, 1s-
